What is an important factor of natural selection?
Variations within a population
Why variations are important in human life?
Variations are the basis of evolution, but variations within a population create diversity, which is useful to slow disease and allow natural selection to occur.
What type of reproduction produces more variations within a population sexual or asexual?
Sexual.
Why do benedicial adaptations spread in a population?
The populations which contain many different beneficial mutants, will be substantial variation in the fitness within the population.
What are differences within a population?
These are the morphological and behavioral variations by individuals within a population of organisms. Check human variation is height and the different way humans behave in similar situations.
Natural selection cannot occur without what?
Variations within a population. Variations mean traits that only certain individuals have that give the individual a greater or lesser chance of reproducing.
What causes variation within a species?
It has adaptations
True or false Darwin observed variations among individuals within a population but he did not realize that these variations were caused by selective breeding?
True, Darwin did realize that the observed variations among individuals within a population were caused by selective breeding. Although he did do a lot of great stuff. He wrote a book called The Origin of Species. You should check it out if you would like to find out the stuff that he did and what he found out about evolution. Either that or rent a book from a library about evolution.
What does the arithmetic population density not tell us?
Arithmetic population density does not provide insights into the distribution of the population within a given area. It does not account for variations in population concentration and can mask disparities in population distribution within a region. Additionally, it does not consider factors such as age distribution, cultural diversity, or economic characteristics of the population.
What is one main propertie used to desribe a population?
The two major properties of all populations is the rise and fall of the population or rather the number of births and deaths that occur within a population.
What is the variety of life found on Earth and the variations within species is called?

What is the major cause of variation within species?
